[ceph-users] remove host from cluster for re-installing it

Hello, On my Octopus cluster with 6 nodes (3 mon/mgr, 3 OSD), I would like to re-install the operating system of the first mon/mgr node. For that purpose I tried "ceph host rm mynode" but then I got the following two health warnings: 2 stray daemon(s) not managed by cephadm 1 stray host(s) with 2 daemon(s) not managed by cephadm So I did not proceed with the re-installation and added the node back. What would be the correct command in order to do that? I can live with mon/mgr which are do not have the quorum for the time of the re-installation. I just need my CephFS to still be available. Right now there is 2 mon daemons running and 1 active mgr and 2 standby mgrs. Thank you, Mabi
